Mbappe Trains in Blackout Next-Gen Nike Mercurial Superfly VI Cleats

Close-up with Kylian Mbappe's blackout prototype football boots.

Mbappe's boots show off what is new about the Nike Mercurial Superfly compared to its predecessor. Most remarkably, the collar features a different cut shape, and the upper also comes with many changes comapred to the fifth generation that was launched ahead of the Euro 2016.

Interestingly, Kylian Mbappe is currently using the Nike Mercurial Vapor 12 football boots and also tested the all-new, knitted next-generation Nike Mercurial Vapor 2018 World Cup cleats in training around one month ago. In fact, the next-gen Nike Mercurial Superfly and Vapor are almost identical, with the only difference the height and shape of the collar.
